Material Notes:
The AL 436S™ alloy has a body-centered cubic, ferritic microstructure at all temperatures below the melting point. Angular titanium carbo-nitiride particles occur randomly in the ferrite matrix microstructure. Weldability of the AL 436S™ alloy is similar to that of other stabilized ferritic alloys. GTAW (TIF), GMAW (MIG), high frequency and spot welding procedures are applicable. Conventional inert gal shielding is required for tungsten or metal arc processes. Properly welded, the AL 436S alloy retains corrosion resistance and most of the mechanical properties of the base metal in the weld deposit and heat-affected zone. Weld deposits are fully ferritic and free of martensite.Information provided by Allegheny Ludlum Corporation.
